Month: 2026-04. Focus: compatibility updates in ocaml/opam-repository to support OCaml 5.5 and Rocq 9 for Why3 1.8.2. This work reduces upgrade friction and ensures downstream users can build against newer OCaml toolchains without breaking dependencies. Implemented by updating dependency constraints to reflect Why3 1.8.2's compatibility; commit b71aa82a55dcdea58807490055d715314f36ffde: 'Mark Why3 1.8.2 as compatible with OCaml 5.5 and Rocq 9.' No major bugs fixed in this period per scope. Overall impact: improved stability and upgrade path for OCaml ecosystem users; enhanced packaging reliability in opam-repository. Technologies/skills demonstrated: dependency management, OCaml ecosystem versioning, changelog-quality commits, precise commit messaging, cross-version compatibility considerations.

March 2026 monthly summary for ocaml/opam-repository focusing on business value and technical achievements. Key release: Rocq 9.2.0 delivered with developer tools, an IDE and server integration to enhance theorem proving workflows and user interaction. Implemented a compatibility guard to mark rocq-stdlib 9.0.0 as incompatible with Rocq >= 9.2, reducing upgrade/pairing issues and guiding users toward stable configurations. Overall, improvements contribute to reliability, smoother onboarding for advanced users, and a stronger foundation for future tooling enhancements.

February 2026 monthly summary focused on delivering stable packaging, compatibility, and ecosystem usability for Coq and Rocq workflows, with concrete improvements across coq/opam and ocaml/opam-repository. Key outcomes include hardened OPAM packaging for Flocq 4.2.2 and Gappa 1.8.0 with dependency bounds to improve rebuild reliability, introduction of Rocq Prover UX compatibility binaries and simplified constraints to boost usability, and WebAssembly-enabled workflows via Coq-wasm 9.1 compatibility. Dependency stabilization was achieved by removing development-version exceptions, aligning with officially supported Coq/Rocq versions. Interval arithmetic and decision procedures were enhanced through Coq Interval 4.11.4, and Rocq binaries/metapackages were prepared to streamline adoption in the opam-repository.

Concise monthly summary for 2025-10 focusing on business value, technical achievements, and repo health for ocaml/opam-repository.

July 2025 monthly summary for coq/opam focused on release engineering and dependency modernization. Key features delivered include Rocq Prover packaging and release improvements enabling the 9.1+rc1 release, and library updates for Coquelicot 3.4.4 and coq-interval 4.11.3. Major fixes were packaging cleanup and removal of the deprecated rocq-prover package, with updated metadata/URLs to align with the new release strategy. Impact: improved release readiness, build reproducibility, and dependency hygiene, reducing downstream risk. Technologies/skills demonstrated: packaging automation, release engineering, dependency management, versioning, and metadata management.

June 2025 monthly summary focusing on Coq/opam packaging improvements to enable installation and management via opam for Coq-related libraries.

April 2025: Delivered metadata standardization for the coq/opam repository by homogenizing package category tags to a consistent taxonomy, improving consistency, searchability, and maintainability of the package index. Change scoped to category metadata with a single commit.

February 2025 monthly summary for coq/opam. Key outcomes include: 1) Gappa Prover Packaging: added Gappa support library 1.7.0 to opam with a dedicated opam file detailing dependencies, build steps, and metadata (commit ea8a04d63a032b725c7388149e2c4931b371290f). 2) Compatibility constraint update: restricted coq-menhirlib versions to Coq < 8.19 to prevent installations with incompatible Coq 8.19 and later (commit 92aa5b098a053aa592922f998ba3659d31c4774d). 3) Enhanced opam-coq-install-remove: display removed/installed files after removal by running opam show --list-files and filtering by relative paths (commit 116fb70ddc39c48878f2878d982ddaa2fce660ae).

January 2025: Implemented opam packaging and Coq-version compatibility for Gappa, Flocq, Coquelicot, and Coq-Interval in the coq/opam repository. This delivers reproducible builds, streamlined dependency management, and improved stability for the Coq ecosystem. The changes establish Coq-version upper bounds across multiple packages to guard against breaking changes and facilitate smoother CI and onboarding for upstream users.
